I was just messing around with the modalBottomSheet layout on my app and got this error:

The following assertion was thrown during performLayout():
'package:flutter/src/rendering/object.dart': Failed assertion: line 1706 pos 12:
'!_debugDoingThisLayout': is not true.

Either the assertion indicates an error in the framework itself, or we should provide
substantially
more information in this error message to help you determine and fix the underlying cause.
In either case, please report this assertion by filing a bug on GitHub:
https://github.com/flutter/flutter/issues/new?template=2_bug.md

The relevant error-causing widget was:
ListView
file:///**********/lib/screens/add_server_screen.dart:25:16

The code below starts at line 25 where the error is indicated.

I'm only filing the bug because it asked me to do so :) no need for a resolution on my end, I was just experimenting

Here is the widget that threw the error

code snippet 
child: ListView(
          // reverse: true,
          children: [
            Center(
              child: Text(
                'Server Name',
                style: kTextStyleServerTile,
              ),
            ),
            TextField(
              autofocus: true,
              textAlign: TextAlign.center,
              onChanged: (value) => name = value,
              selectionWidthStyle: BoxWidthStyle.max,
              decoration: InputDecoration(
                focusColor: Colors.lightGreenAccent,
              ),
            ),
            Row(
              children: [
                Column(
                  children: [
                    Center(
                      child: Text(
                        'Split Metric',
                        style: kTextStyleServerTile,
                      ),
                    ),
                    TextField(
                      autofocus: true,
                      textAlign: TextAlign.center,
                      onChanged: (value) => points = value,
                      selectionWidthStyle: BoxWidthStyle.max,
                      decoration: InputDecoration(
                        focusColor: Colors.lightGreenAccent,
                      ),
                    ),
                  ],
                ),
                Column(
                  children: [
                    Center(
                      child: Text(
                        'Tips Earned',
                        style: kTextStyleServerTile,
                      ),
                    ),
                    TextField(
                      autofocus: true,
                      textAlign: TextAlign.center,
                      onChanged: (value) => tips = value,
                      selectionWidthStyle: BoxWidthStyle.tight,
                      decoration: InputDecoration(
                        focusColor: Colors.lightGreenAccent,
                      ),
                    ),
                  ],
                ),
              ],
            ),
            TextButton(
              onPressed: () {
                Provider.of<ServerData>(context, listen: false).addServer(
                  name,
                  double.parse(points),
                  double.parse(tips),
                );
              },
              style: ButtonStyle(
                backgroundColor: MaterialStateProperty.all(kAccentColorOrange),
              ),
              child: Text(
                'Add Server',
                style: kTextStyleServerTile,
              ),
            ),
          ],
        ),

and here is the rest of the error:

Hi @SlowGen
Thanks for filing the issue, this is caused by nested rows and columns, if you provide a specific size, the error will go away. You check your logs for hasSize error
Closing, as this isn't an issue with Flutter itself. If you disagree, please write in the comments and I will reopen it.
Thank you
